Wong" Cc: linux-xfs@vger.kernel.org, linux-fsdevel@vger.kernel.org Subject: [PATCH 03/12] iomap: pass flags to iomap_file_buffered_write_punch_delalloc Date: Tue, 10 Sep 2024 07:39:05 +0300 Message-ID: <20240910043949.3481298-4-hch@lst.de> X-Mailer: git-send-email 2.45.2 In-Reply-To: <20240910043949.3481298-1-hch@lst.de> References: <20240910043949.3481298-1-hch@lst.de> Precedence: bulk X-Mailing-List: linux-xfs@vger.kernel.org List-Id: List-Subscribe: List-Unsubscribe: MIME-Version: 1.0 X-SRS-Rewrite: SMTP reverse-path rewritten from by bombadil.infradead.org. See http://www.infradead.org/rpr.html To fix short write error handling, We'll need to figure out what operation iomap_file_buffered_write_punch_delalloc is called for. Pass the flags argument on to it, and reorder the argument list to match that of ->iomap_end so that the compiler only has to add the new punch argument to the end of it instead of reshuffling the registers.
